UNITED STATES PATENT oFFIc THOMAS M. WILSON, OF IHILADELPHIA, PENNSYLVANIA.

name.

Be it known that I, THOMAS M; WILSON,

. a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Driers,of cation.

My invention relates to improvements in driers, more particularly designed for drying brick and the like, the object of the invention being to provide an improved construction, whereby an improved radiation 1 of heat is had to insure a more perfect dryair, whereby said metal radiators radiate ing operation. a s

A further object is to provide a drier having an improved arrangement of fines, air spaces and passages in combination with metal radiators interposed between the fines for smoke and gases and the passages for into the air passages the maximum heat units of the fuel consumed.

A further object is to provide in combination with radiators, an improved ar-- rangement of fines and passages, whereby the brick may be heated more uniformly and in less time than'heretofore, and embody in such construction of drier, slip joint furnace crowns and other structural details,

whereby a drier superior in many ways to.

driers in general use is had.

With these and other objectsin View, the

invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims. a

13, is a staggered view in vertical transverse sect-ion through the stack. Fig. 14, is an enlarged fragmentary vertical transverse section illustrating the fines, fioors and rails, and Figs. 15, and 16, are enlarged detail views illustrating the rail joint or connections.

' My improved drier is'made with a series of parallel longitudinal tunnels 1, having suitable doors 2 at the ends, and provided with tracks 3 to support the cars (not shown which are moved through the drier. The ralls 3 are supported on transverse rails 4, extending through the drier, and posi- .tioned above the fioor.

.to the heat, and prevent injury due to this cause. That portion of the crown 7 which is directly over the furnace, is, as a matter of fact, the furnace crown proper, islower than the crown 8 which extends rearwardly from the furnace, and is really a fiue crown. Therefore, for convenience of description,

the lower .crown I shall termthe furnace crown, and the higher crown, the flue crown. This different elevation'of crowns provides a relatively large air chamber 10 above each furnace, which communicates with a longitudinal air fine 11, which extends throughout aportion of the tunnel fioor and communicates therewith by means of openings 12. These openings 12 are formed by leaving out tiles in the fioor, and the said tiles 13 are supported in transverse angle irons 14.

The crowns 8 above referred to. form covers for main fire fiuesl15, which are divided by longitudinal cords 16, and are made with laterals 17'at'their ends, communicating with fines '18 in stack 19 at the 'rear end of the drier.

Between the furnaces 6 and the fines 15, hollow bridge walls .20 are provided. These bridge walls 20 have inlet fines 21 which of such structures.

extend through the front wall of the drier, and they communicate with vertical flues 22 beside the tire and smoke flues 15, and are adapted to direct the air into the air space 11. In the walls, between the several furnaces, vertical flues 23 are provided'which connect the air spaces 10 with horizontal inlet fiues 24, the latter extending through the front wall of the drier and located above the fiues 21.

In the crowns 7 and 8, radiator support ing tiles 25 are built, and constitute a part By reference particularly to Figs. 10, 11, and 12, it will be seen that these tiles 25 operate as keystones of the arch, and extend above the arch and into the flanged lower ends 26 of hollow radiators 27. These radiators 27 are preferably castings, having open bottoms 28 communicating with openings 29 in the tile 25. The upper edge of each radiator is provided with an outwardly projecting notched flange 29 to support a ribbed cover 30. This ribbed cover 30 is also notched at its edges, and in'the notches of the cover and the flange, bolts 31 are secured by nuts 32, so as to render the radiators airtight. The smoke and gases from below fill the radiators and the metal rapidly radiates the heat into the air spaces above. One set of radiators (the front set) heats the air in the passage 11, which of course, is also assisted by the rear radiators, but the latter discharge the greater portion of their heat directly into the tunnels. The floor 13 of each tunnel also serves as a radiating medium for the heat, but the metal radiators greatly increase the radiation of heat and utilize to a maximum degree the heat units in the fuel. The stack 19 also constitutes an outlet for the air from the several tunnels, the roofs of said tunnels having dampered communication 33 with said stack.

In operation, air enters the fines 24, passes up the vertical flues 23 in the partition walls between the furnaces and. dis charges into the chambers 10. It is, of course, heated in this passage to the chamber 10, and is further heated by the front radiators 27 The chambers 10 and 11 constitute an air heating space located between the furnace crown and the floor of the drier, and while, of course, the air is heated in its passage to this chamber, it receives in the chamber the maximum of heat units before discharging into the drier. By reason of the shape of the crown, the air which passes up through the walls is deflected over toward the center where it comes into contact with the highly heated air about the radiators as shown in Fig. 6, and escapes through the floor directly under the cars in a highly heated condition. This highly heated air passes up into the front ends of the several tunnels, and then travels longitudinally of the tunnels to the rear ends. Air also enters the fines 21, passes through the hollow bridge wall 20, up through the vertical flues 22 into the passage 11, and from thence into the tunnels. The heat, therefore, enters the tunnels at their forward ends, and this heat which is stored in the air, insures a continuous maximum supply of hot dry air to the bricks in the several tunnels, and this air rapidly takes the moisture from the bricks, and escapes up the stack 19. By reason of the metal radiators in communication with furnaces and the smoke fiues, a rapid interchange of temperatures is had between the smoke and gases, and the air on the opposite side of the radiator. The heat units are therefore rapidly transferred, so that the incoming air is highly heated. The radiation through the tile or brick of the several fines is also utilized, but the metal radiators insure a more rapid transfer of the heat units, and assist the radiation from the brick and tile in utilizing a far greater percentage of heat units of the fuel, than has been possible with driers of this kind as heretofore made.

Various slight changes might be made in the general form and arrangement of parts described without departing from my invention, and hence I do not limit myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of the appended claims.
